Results of finger extension reconstruction in hemiplegic patients after stroke by transferring the flexor carpi radialis branch to the posterior interosseous nerve

FCR-to-PIN nerve transfer alleviates spasticity and partially restores finger extension in patients with limited recovery following contralateral C7 nerve transfer. Although full motor recovery was not achieved, these findings offer promising clinical implications. Overall, the results support the procedure's value in clinical practice. Further studies with larger cohorts are needed to confirm these results and elucidate underlying mechanisms.
